Application led February 16, 1920. Serial No. u359,112.

To all whom it may concern.'

lle it known' that I. CHARLES A. "Arrz, a

citizen of the United States, residing at Iiouseville. in the county of Venango and State of Pennsylvania, have invented new and useful Improvements in Pumps, of which the following is a specification.

The invention relates more particularly'to pumps adapted `to o il wells and is particularly advantageous in connection with oil wells in which the working barrels have become deficient. In this connection the trapping of the sand is particularly desirable and this invention accomplishes this purpose in a simple manner. The other features of the invention will appear from the specification and claims.

yThe invention is illustrated in the accompanying drawings as follows Fig. 1 shows a vertical central section through a pump.

Fig. 2 a bottom View of the clutch element on the same.

Fig. 3 a side elevation of the top of the working barrel.

1 marks the strainer, 2 the standing valve fitting at the top of the strainer, 3 the original working barrel tube` 4 the original standing valve, 3 a coupling at the upper end ofthe orginal working barrel, and 3b thek well tubing. These are of usual construction.

The inserted working barrel 5 has a stend ing valve fitting 6 at its lower end in which a standing valve 7 is` arranged. An intake tube 8 is secured-to the fitting 64 and extends downwardly preferably to Within the original working barrel tube. It is anchored in the original working barrel tube and has a closure formed by cups 9 which are preferably arranged intermediate the ends of the original working barrel tube. A closure cap 10 rests on the upper end of the Working barrel. It has a bevelled bottom 11 and is ot a size approximating the size of thetub- A coupling 12 is arranged in the inr 3". intake tube '8 and this coupling rests on the cap 10. The distance between the closure 9 and the coupling 12 is such as to give some freedom ot' movement so that the cap 10 may be jai-red loose if necessary.

A sand trap pipe 13 is secured to the cap 12 and extends upwardly surrounding the inlet tube 8. It will be understood that thel inlet tube may be made oi any length desired so as to give the sand trap the greatest capacity possible. In some wells the height ot'l the inserted barrel may be well above the originatbarrel tube. In other wells it may be necessary to lower the inserted barrel to nearer the elevation of the original barrel tube and this limits to some extent the length of the sandtrap.

A working plunger 14 is arranged in the inserted barrel and a sucker rod 15 extends upwardly from the plunger. The sucker rod passes through a cap 16 at the upper end of the barrel, this cap having lateral openings 16a so that the pumped liquid may pass out into the tubing. Corrugations 17 are arranged on the upper part of the cap, these forming clutch elements which are adapted to engage corrugations 18 on the underside of a coupling-19 on the sucker rod.- The c011- pling is so distanced Jfrom the plunger that the clutch elements may be brought into engagement before .the plunger'reaehes the standing valve. The purpose of this is to permit of putting a certain amount of strain on the joints of the sucker rods so that they ma be tightened or loosened.

t will be noted that the cap 16 prevents the settling of the sand into the Working barrel after the cessation of the pumping ac-V tion. The sand as it se-ttlesbac-k into the column of oil in the tubing, therefore, settles into the sand trap 13. The cap 10 prevents the settling of the sand on the anchor or closure-9. Consequently if it is necessary to pull the pump there is not a great deal of difficulty in loosening the packing 9. If there is sand outside the sand trap the jarring against the cap 10 by thev packing 9 will i loosen this.

The bottom of the cap 10 being bevelled provides a means by which any scale or irregularities in the tubing may be removed, that is to say, the cap 10 may be driven through such reduced portions, thus clearing the way for the sand trap and for the other parts of the device.

What I claim as new is 1. In a ump, the combination of a tubing; a wor ing barrel within the tubing; a

plunger within the barrel; a cap on the barrel with lateral openings discharging into the tubing, said cap having clutch elements on its upper surface; a rod secured to the plunger and extending through the cap, said rod having an enlargement with a clutchelement adapted to operate on the clutch element on the cap.

2. In a pump, the combination of'a tubing; a working barrel within the tubing; an intake tube extendingA downwardly from the Working barrel within the tubing, the intake being anchored and provided with a closure relatively to the tubing; a plunger within the barrel; and a sucker rod'secured to .the plunger.

4. In a pump, the combination of a tub-v ing; a Working barrel within the tubing; an intake tube `extending downwardly from the working barrel within the tubing, the intake being anchored andY provided with a closure -relatively to the tubing, the space surround- 'ing the intake tube forming a sand'trap; a

cap arranged on the upper end of the working barrel; a plunger in the working barrel; and a sucker rod extending through the cap.

5. In a pump, the combination of a tubing; a working barrel tube secured to the tubing; an. insert working barrel arranged above the working barrel tube; an intake tube extendin from the insert working barrel downward y to Within the working barrel tube; and a closure on the intake arranged in the working barrel tube. h

6. In a pump, the' combination of a tub*- ing; a working barrel tube secured to the tubing; an insert working barrel arranged above the working-barre tube; an intake tube extending from the insert working barrel downwardly to within the working barrel tube; a closure on the intake arranged in the working barrel tube; and meansyon the intake tube resting on the top of the working barrel tube.

7. In a pump, the combination of a tub-A ing; a working barrel tube securedv to the tubing; an insert working barrel an intake forthe insert working barrel extending from the insert working barrel downwardly to Within the working barrel tube; aeap on the working barrel tube throu h which the intake tube extends; and a shou der on the intake tube resting on the'.eap, said shoulder being distanced from a closure to provide a jar for the cap, l

- 8. In a pump, the combination of a tubing; a working barrel Within the tubing; a plunger within the working barrel; an intake tube Aextending downwardly from theworking barrel; a closure and anchor in the tubing from which the intake extends; and a sand trap below the workin barrel and above' the closure and surrounding the intake tube.

9. In a. pump, the combination of a tubin g; working barrel tube secured to the tubing; an insert Working barrel; an intake tube extending from the insert working barrel downwardly to within the workin 4barrel tube; a cap resting on the working arrel' tube through whichl the intake tube extends; and a sand tra carried by surrounding said) intake tube.

10. In a pump, the -combinationof a tubthe cap and ing; working barrel tube secured to the tublng; an insert working barrel; an intake tu e extendin from the insert Working barrel downward y to within the working barrel tube; a cap resting on the working barrel tube through which the intake tube extends; a sand trap carried by the cap and surrounding said intake tube; a closure on the intake tube within the working lbarrel tube; and means on the intake tube restingon the cap,

the distance between the closure and the means being sufficient to permit Vof a jarring of the cap.

In testimony whereof I have hereunto set my hand.
